Oracle Developer Senior interview questions

This is worst interview I ever faced.I reached the Whitefield office as per the schedule time & after 30 mins two person came for the technical discussion.I already knew that interview will be tough.They started asking core java questions which I unable to answer few questions.They started making fun of me in front of me.They are laughing at me & repeatedly saying you don't know anything man.Then they gave me program to write & I did.But still they didn't satisfy with that & they continue to laugh at me.I get so tensed & after that I was unable to answer anything. I told them to stop the interview as I am not comfortable with you guys.They Started giving lecture to me as you don't know anything ,why you came for interview .I already had two offer & I mentioned there too to shut their mouth & I came out of interview. It was really a bad experience for me .From the next time I will never go for Oracle interview.
